You may never see one of these again. Here is a very good description of this machine from Wikipedia. The Kenbak-1 is considered by the Computer History Museum. And the American Computer Museum. To be the world's first personal computer.
Only 50 machines were ever built using Bud Industries. Enclosures as its housing per the Oral History of John Blankenbaker. Today only 14 machines are believed to exist worldwide. In the hands of various collectors. Production of the Kenbak-1 stopped in 1973. As Kenbak failed, and was taken over by CTI Education Products, Inc. CTI rebranded the inventory and renamed it the H5050, though sales remained elusive. Since the Kenbak-1 was invented before the first microprocessor.

The machine didn't have a one-chip CPU. But instead was based purely on small-scale integration. S type 1404 silicon gate. Equivalent to an instruction clock speed of 1 MHz.

, but actual execution speed averaged below 1000 instructions per second due to architectural constraints such as slow access to serial memory. It may yet be completed and this listing could end at any time. I can't remember the curators name but he had the biggest Kenbak collection in the world.

The last photo is of him inside the museum displaying this Kenbak -1. Very few exist and this is NOT a reproduction. I have not tested this in any way as it should be looked over by a prefessional before initial power-up. Although at the time, I was told it functioned. Unit is in excellent condition considering its age and rarity.

Missing 1 rubber foot and has a few scuffs and scratches. Also are 2 cds included with various information a apparantly a training course for the Kenbak. I also include the original photo of the curator of the museum. If you can afford this, you can afford a plane ticket. Please look at the photos as they are a large part of the description.
